PLOW.

specification My invention relates to new and useful improvements in plows, and more particularly to such plows as are mechanically o perated. l

The object of the invention is to provide a device of the character described which carries its own motive means, and which is provided with its own steering, traction and feed mechanism; as well as one whose carrying wheels are laterally adjustable and whose supporting frame and the mechanism carried thereby are vertically adjustable on its axles. l Another feature resides in the provision of means for imparting to the plow-share a lateral, or rocking motion whereby when the same becomes embedded in the soil, it may be loosened from its bed, by the operator, through the operation of a hand lever, connected with the plow beam.

Finally the object of the invention is to provide a device, of the character described, that will be strong, durable, eiicient,A compact and one which -will be easily operated and easily kept in repair.

With the above and other objects in view, my invention has particular relation to ce1:- tain novel features of construction and operation, an example of which is given in this specification, and illustrated in the accompanying drawings. wherein Figure 1 is a side elevation of my device, in its entirety. Fig. 2 is a plan view thereof. Fig, 3 is a sectional view, taken on the line (z-a of Fin'.

ence designate similar parts, in each of the figures, the numeral 1 refers to a supporting frame, which is composed of'suita'ble side and end members and which is supportrear axles '2 and 3 which, in turn, are carried b v suitable 'front and The supporting frame 1 is provided with cross braces 1, 5, and 7 for supporting the mechanism appendant thereon. The supporting trame carries an engine S which is designed to iurnish the motive power for the plow.

From

this engine a drive shaft 9 extends rearwardly and operates in suitable bearings 10 and 11 carried by braces 5 and G. This shaft is provided with a worm gear 1Q which is adapted to engage gear wheel '13 which is rigidly mounted on shaft 14 carried by the supporting frame 1. This shaft 1li is revolubly secured to said tra me by suitable bearings and extends on either side, beyond the frame, and carries, at its extremities,

sprocket wheels 15 and 16 rigidlymonnted c thereon. These sprocket wheels are connected to sprocket wheels 1T and 18 rigidly mounted upon the hubs of the rear wheels of the plow, by means of sprocket chains 19 and 9.0, and are adjustable, laterally, `thereon, so as to be readily kept. in alinement. with sprocketwheels 15 and 16. Thns a traction mechanism is provided for the plow.

The numerals 21 and l2 designate two suitably curved, downwardly extending, channel irons, which are secured to brace (3. lVithin the channels of these irons, a block 23 is adjustably secured by means of a rod This block is designed to be raised and lowered by means of said rod and carries a segment 25 which serves as a bearing for the end of the plow-beam 26, which passes through said segment and is secured therein in any suitable manner. rlhis segment also carries a rack for a purpose hereinafter set forth` This plow-beam extends rearwardly and curves downwardly and carries a share 27 of any desirable type. The rod 24 is sccured,lat its upper end tothe front eX- tremity of a shifting lever Q8 which is pivoted to the plow-frame at a point intermediate the ends thereof. 4The rear end of' this shitting lever is connectedto the frontend of the lifting lever 29, by means of a slidinor hin e as shown in Fig. 1 The rear 'end o? the ever- 29 is attached to theplow beam 26, and is attached, at a pointv mter- Aaccomplished through the mediate the caos thereof, to the arch of rear axle 3 said attachment serving as a fulcrmn for said lever. The lever 28 carries a suitable handle 80 which is held in any desired position by the usual rack-and-dog arrangement 31. By a backward manipulation of handle the front end of the plow beam 2o is elevated, through the operation of rod 2t and block 23 and thus the point of the share is also elevated and the feed of the plow thus controlled. By a further rearward-manipulation of said handle the rear end of the lever 28 is depressed and the rear end of lever 29 raised, anql the plow may thus be raised, entirely out of the ground, by the proper-manipulation of said handle 30. I have also provided for a lateral or rocking motion for the plow share. Thisl may be agency of a hand lever 32, which is rigidly secured to the front end of the plowbeam 26, and which -has a movement transversely of the mam Ybar a lateral movement.

supporting frame. y

The steering mechanism comprises a' rod 34, revolubly secured in bearings on braces, 5 and 6 of the supporting frame, and which is provided with a hand lever 3'5 for rotating the same. with the usual rack-and-dog arrangement 3G, for holding the same in The front end of this rod carries an arm 57, rigidly attached thereto, and to the end ot' which, a link 38 is hinged. This link con neets with the arm 3S) of the segmental rack l0 which is pivoted to the framework of the plow. The steering mechanism also includes the transverse bar ell which is secured tothe arch 45, which supports the front axles, by means of eapstan-screws, or bolts ll2 which pass through slots in said bar, and also through said arch, thus allowing the rl`his bar is, also, provided with rack teeth designed to mesh with the segmental rack ll0, and to each end of said bar a link 43 is hingedly attached. These links also have hinge connections with rearwardly-extending arms 44, carried b the axles of the front' or guide wheels of the plow, and rigidly attached thereto, as is more accurately shown in Figs. 2 and lt is obvious that, by a manipulation of hand lever 35, the rod 34. will be turned and the segmental rack l0 will, through the opera tion. of arm 37 and link 38, be caused to ro tate on its pivotal attachment to the framework. Any movement of the rack 1-() will be transmitted to bar 4l and through link 1liand arm 4,4 to the main guide wheels. ik simple and elllcient steering mechanism is thus provided.

.fsire to call special attention to the form of axle shown. lach guide wheel has` its own axle 2 and these axles are connected by a suitable, laterally adjustable varch 45. This arch is secured to said axles by'means This hand lever is piovidcdy l l l any desired position. i

of ties 46' and -ft which are integral with the axles, but through which the arch may slide, vertically. The ties 4T are provided with set screws 4S, which are provided for the purpose of engaging with said arch and securing the same at any desired point of verti lal adjustment. The lateral adjustment of this arch is provided for by the mechanism shown in detail in Figs. l and 5, in which the numeral #ttl refers to a brace of channel iron within the channel of which the members of the arch are secured by crossbolts 50. These members play upon rollers 5 1 located therebetween and the inner sides ot' said members are provided with rack teeth which mesh with corresponding teeth of a pinion 52 which carries a hand crank. l t is obvious that the arch can be adjusted laterally by merely turning said crank. The rear axles 3 are connected to an arch, substantially similar, in all respects, to the arch 45, and is vertically adjustable on said axles, yas well as having the lateral adjustment above described. By reason of this lateral adjustment, the plow can be made to accommodate itself to rows of plants of varying distances from each other; and by reason ot' the vertical adjustment of the arches the plow mafv be made to aecommodale itsel't| to any character of Surface, whether level or sloping. The supporting frame carries also a seat 53 for the operator and a conveniently located throttle lever 54 by means of which the engine is.controlled.

Provision is made whereby the main supporting frame may have a rocking motion ou the front arch. This end is accomplished by means ot' bearings 55 and 56 wlneh eX- tend downwardly from the main frame, one in front and the other-in the rear, of said arch and also a bearing 57 which is carried by braces which extend rearwardly from the arch. These bearings are in alinement. with each other and also in alinement with a bearing 58 which extends upwardly from arch and upon which the supporting trame rests. A linch-pin passes through all ot these bearings and is securely keyed therein and thus the supporting' frame is secured lirmly to the front. arch but at the same time is allowed a free rocking motion thereon.

A plow constructed in accordance with the description above set out', Will be found t0 be not only compact and practical; but also will be easily operated and readily adapted to the cultivation of various crops, irrespective of the width of the rowsor the varying condition of the surface of the land to be cultivated.
